Description
Technical Field
[0001] This utility model relates to the technical field of elevator guide rail cleaning equipment, specifically to a guide rail cleaning device for a box elevator. Background Technology
[0002] The operation of a box elevator relies on guide rails for guidance and support. Dust, stains, metal shavings and other impurities on the outer wall of the guide rails will increase the elevator's running resistance, accelerate the wear of the guide rails and guide shoes, affect the stability and safety of the elevator's operation, and may even cause malfunctions in severe cases. Therefore, it is necessary to clean the elevator guide rails regularly.
[0003] In current technologies, when cleaning the guide rails of a box elevator, the angle grinder is usually fixed to the maintenance platform using a support frame. The brush disc on the angle grinder is then placed on the surface of the guide rail sidewall. By slowly moving the elevator up and down, the brush disc on the angle grinder moves along the sidewall of the guide rail, brushing away the dust on the sidewall and thus achieving the purpose of cleaning the guide rail sidewall.
[0004] However, in fixed-installation angle grinders, the brush discs are mostly fixed to the outside of the maintenance platform. Although this makes it convenient to clean the guide rails, it also causes the brush discs to be exposed and easily attract dust. Over time, this will reduce the cleaning effect on the guide rails. To solve the above problems, a guide rail cleaning device for box elevators is proposed. Utility Model Content
[0005] In view of this, the present invention provides a guide rail cleaning device for a box elevator. The present invention uses a manually rotated angle grinder to rotate the rotating block connected to it 180° on the corner base, so that the angle grinder is rotated to the side away from the guide rail. The grip of the angle grinder is placed on the other side of the support frame by the support pad. Then, the threaded rod drives the slider to move towards the baffle side, so that the brush plate is inserted into the storage groove for storage, preventing dust from falling onto the brush plate, thereby improving the service life of the component.
[0006] To solve the above-mentioned technical problems, this utility model provides a guide rail cleaning device for a box elevator, including guide rails arranged on both sides of the car, an inspection platform arranged on the top of the car, a cleaning window arranged on the left and right sides of the inspection platform, each cleaning window corresponding to a guide rail, a slide rail arranged on the inner side of each cleaning window, a baffle arranged in the middle of each slide rail, a moving part arranged on the front and rear sides of the baffle rail, the moving part slidingly adapted to the slide rail, a flipping component arranged on the upper part of each moving part, a cleaning component fixedly arranged on the bearing end of the flipping component, and a storage groove arranged on the front and rear sides of the baffle rail.
[0007] Each moving part includes a slider that is adapted to slide along the slide. The slider is used to move the corner base on the slide. A corner base is fixedly installed on the upper part of each slider. The corner base is used to install a flip block, so that the flip block can be rotated 180°. The corner base is U-shaped. A threaded hole is provided at each end of the slide. The threaded hole is used to install a threaded rod, so that the threaded rod can rotate. A threaded rod is provided in each threaded hole. The threaded rod is used to drive the slider to move in the slide. The threaded rod is connected to the slider by a nut.
[0008] Each flip assembly includes a flip block that fits into the notch of the corner base. The flip block is used to rotate the mounting bracket, so that the cleaning assembly installed on the mounting bracket can be rotated 180 degrees. The flip block and the corner base are rotatably connected by a pivot. A mounting bracket is provided on the side of the flip block near the guide rail. The mounting bracket is used to install the cleaning assembly.
[0009] The cleaning assembly includes an angle grinder mounted on a bracket near the guide rail. The angle grinder drives a brush to rotate. The brush is mounted on the rotating end of the angle grinder and is used to clean the elevator guide rail. The brush is detachably connected to the rotating end of the angle grinder.
[0010] Each angle grinder has a support pad underneath its grip. The support pad supports the angle grinder, reduces the stress on it, and allows the angle grinder to be connected to the support frame. The grip of the angle grinder passes through the cleaning window. A support frame is located at the bottom of each support pad. The support frame connects the angle grinder to the corner base, providing support for the angle grinder. The support frame is fixedly connected to the side wall of the corner base. A limiting plate is located on each of the left and right sides of the support pad. The limiting plate is used to clamp and limit the angle grinder grip.
[0011] The baffle is L-shaped, and a storage slot is fixedly installed on the front and back sides of the long side of the baffle. The storage slot is used to store the brush plate, so that the brush plate will not be exposed to the outside of the equipment when it is not working, thereby extending the service life of the component. The storage slot is circular and fits the brush plate.
[0012] A battery compartment is located on the side of the storage slot away from the guide rail. The battery compartment is used to house the power module and prevent dust from falling on it. The power module is detachably installed inside the battery compartment. The power module is used to power the angle grinder. The power module is electrically connected to the two closest angle grinders via cables.
[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By manually flipping the angle grinder, the flipping block connected to it is rotated 180° on the corner base, so that the angle grinder is flipped to the side away from the guide rail. The grip of the angle grinder is placed on the other side of the support frame through the support pad. Then, the threaded rod is used to drive the slider to move the slider towards the baffle side, so that the brush plate is inserted into the storage slot for storage, preventing dust from falling onto the brush plate and thus improving the service life of the parts.
[0014] 2. By manually flipping the angle grinder, the flipping block connected to it can be rotated 180° on the corner base, so that the angle grinder is flipped to the side away from the guide rail. The flip-and-store design can prevent the angle grinder from being suspended on the sides of the guide rail for a long time, thereby improving the service life of the components.
[0015] 3. Adjust the position between the slider and the guide rail by adjusting the threaded rod, thereby moving the flipping component installed on the slider. This adjusts the distance between the angle grinder and the guide rail on the cleaning component, allowing the brush plate installed on the rotating end of the angle grinder to be adjusted to the area in contact with the outer wall of the guide rail. Then, start the angle grinder synchronously to move it, thus completing the cleaning work of the guide rail. This makes it easy to adjust the distance between the brush plate and the surface to be cleaned on the guide rail, thereby improving the usability of the equipment. Attached Figure Description
